Copper-catalyzed 1,3-dipolar cycloaddition of methyleneindolinones and N,N＇-cyclic azomethine imines
摘要
A copper-catalyzed stereoselective 1,3-dipolar cycloaddition of methyleneindolinones and N,N0-cyclic azomethine imines has been developed under mild reaction conditions.The spiro[pyrazolidin-3,30-oxindoles] were obtained in moderate to high isolated yields(up to 82%) with good stereoselevtivities(up to 15:1) in the presence of 5 mol% of Cu(OAc)2at room temperature.
